The dimensions on these: 3946246 rectangular mounts:
http://www.gmpartsdirect.com/results...number=3946246
are:
3" long
2.1" wide
3/4" thick
What I currently have on my 65 Burb are 3" long x 1 3/4" wide. Steel spacers are 1 3/4" as well.
I thought these 3946246 were what I needed . . . I believe I can use them, looks like there's room in there between the channel.
Anybody got the dimensions for these from Classic Industries? Wondering if they are 1 3/4" wide vs 2":
